Activision CEO Bobby Kotick appreciates the ongoing shift from physical game sales to digital sales, which has racked up $3 out of every $4 the publisher generates from sales. It's a shift that caught many game developers off guard, but Activision raised its full-year profit and revenue based on strong growth in digital business.

Call of Duty and Destiny helped Activision Blizzard's digital business increase 53.3 percent year-over-year in Q1, according to the company.

"The transition to digital continues to drive our business," Kotick said during a financial call. The digital business is more lucrative to game publishers, and allows gamers to immediately purchase games - without added clutter in their gaming space.

In addition, Hearthstone: Heroes of Warcraft and Destiny now have more than 50 million registered gamers, with more than $1 billion combined in sales. Hearthstone is a free-to-play mobile game that lets users pay for items and in-game upgrades.
